Contrast enhanced computed tomography (CT) of the thorax showed chronic occlusion of the left-sided central veins with the presence of a cervical collateral venous flow from the left to the right side reaching the nonoccluded right-sided central veins, specifically the confluence to the right innominate vein (IV) and, as part of the collateral circulation, a transverse connecting, in parts quite tortuous, and u-shape midline jugular vein measuring about 3 mm in diameter (Figure 1).
